BACKGROUND

The present disclosure relates to the field of wireless communicationstechnologies, and in particular, to a data transmission method andapparatus and a computer storage medium.

In a New Radio (NR) system, a slot or a symbol is used as a schedulingunit, and each slot includes 14 Orthogonal Frequency DivisionMultiplexing (OFDM) symbols. The NR system has a flexible framestructure. There may be a downlink (DL) symbol, an uplink (DL) symbol,and a flexible symbol. The flexible symbol is also referred to as anunknown symbol. The flexible symbol may be rewritten by using signalingfor DL transmission or UL transmission.

DETAILED DESCRIPTION

For ease of understanding of the technical solutions in the embodimentsof the present disclosure, related configuration signaling in theembodiments of the present disclosure are described below.

1) Semi-static UL/DL configuration signaling is used to implementsemi-static UL/DL configuration. Specifically, a slot format within oneconfiguration period (for example, 5 ms or 10 ms) is configured by usingsemi-static RRC signaling. The slot format may indicate quantities andpositions of UL symbols, DL symbols, and flexible symbols in each slotwithin one configuration period.

Further, the semi-static UL/DL configuration signaling includes thefollowing two cases:

1.1) Common semi-static UL/DL configuration signaling is used toimplement semi-static UL/DL common configuration, which is also referredto as cell-specific semi-static UL/DL configuration.

1.2) Dedicated semi-static UL/DL configuration signaling is used toimplement semi-static UL/DL dedicated configuration, which is alsoreferred to as user-specific semi-static UL/DL configuration.

2) Dynamic slot format indication signaling is used to implement adynamic slot format indication. Specifically, the dynamic slot formatindication signaling is carried in a group common PDCCH to be sent, andis used to dynamically indicate a slot format of each slot.

Further, the dynamic slot format indication signaling has the followingtwo indication manners:

2.1) The dynamic slot format indication signaling indicates a directionin each symbol in each slot.

2.2) In combination with semi-static UL/DL configuration, the dynamicslot format indication signaling can only change a direction in aflexible symbol in the semi-static UL/DL configuration but cannot changea direction in a UL symbol and a direction in a DL symbol in thesemi-static UL/DL configuration.

3) Dynamic scheduling signaling is used to implement dynamicallyscheduled data transmission. For example, data transmission scheduled byDCI is physical downlink shared channel (PDSCH)/physical uplink sharedchannel (PUSCH) transmission or physical uplink control channel (PUCCH)transmission that carries an acknowledgement(ACK)/negative-acknowledgement (NACK). For another example, measurementsignal transmission scheduled by DCI is aperiodic channel stateinformation (CSI)-reference signal (RS) transmission or aperiodicsounding reference signal (SRS) transmission. The data transmission ormeasurement signal transmission scheduled by the DCI implicitlyindicates whether its corresponding symbol is a DL symbol or a ULsymbol.

Further, the dynamic scheduling signaling includes the following twocases:

3.1) Multi-slot dynamic scheduling signaling: for example, one piece ofDCI schedules data transmission in a plurality of consecutive slots, andthe same time-frequency resource is used to transmit data in theplurality of slots.

3.2) One-slot dynamic scheduling signaling: one piece of DCI schedulesdata transmission in one slot.

4) UE-specific RRC signaling is used to implement UE-specific RRCsignaling configured transmission, for example, periodic measurementsignal transmission or physical random access channel (PRACH)transmission. UE-specific RRC signaling configured transmission alsoimplicitly indicates whether its corresponding symbol is a DL symbol ora UL symbol. For example, a symbol corresponding to a periodic CSI-RS isa DL symbol, a symbol corresponding to a periodic SRS is a UL symbol,and a symbol corresponding to a PRACH is a UL symbol.

5) Cell-specific RRC signaling is used to implement cell-specific RRCsignaling configured transmission, for example, transmission of SI suchas remaining minimum SI (RMSI) or other SI (OSI). Cell-specific RRCsignaling configured transmission similarly implicitly indicates whetherits corresponding symbol is a DL symbol or a UL symbol.

Referring to FIG. 1 , as a network schedules a terminal to performmulti-slot transmission, data transmission in a slot may encounter thefollowing problems.

1) Transmission resources that can be used to transmit data in a slotare inadequate for scheduling.

For example, the network uses DCI to schedule eight slots to transmit DLdata, and eight DL symbols are occupied in each slot to transmit the DLdata. However, quantities of UL/DL symbols in different slots areflexibly configured. Therefore, the quantity of DL symbols in a slot maybe less than the quantity of DL symbols required for scheduling.

In FIG. 1 , DCI in a slot 1 schedules DL transmission in eight slots.Each slot occupies eight symbols. A quantity of usable DL symbols in aslot 3 is less than eight. In this case, how to transmit DL data in aslot is a problem to be resolved in the embodiments of the presentdisclosure.

2) A resource used to transmit data in a slot is already occupied byanother resource.

For example, in a slot 4, some resources used to transmit data are usedto transmit SI such as a synchronization signal block (SSB), RMSI orOSI. In this case, how to transmit DL data in a slot is a problem to beresolved in the embodiments of the present disclosure.

3) A resource used to transmit data in a slot is already occupied bydynamic one-slot scheduling.

For example, in a slot 6, there is dynamically scheduled one-slottransmission, and the one-slot transmission occupies some resources formulti-slot transmission. In this case, how to transmit data is a problemto be resolved in the embodiments of the present disclosure.

4) A transmission direction of a resource used to transmit data in aslot is opposite a transmission direction indicated by a slot format.

For example, in a slot 5, a slot format indicates that a slot includestwo DL symbols, two flexible symbols, and 10 UL symbols. A symboldirection of some resources used to transmit data is opposite a symboldirection indicated by the slot format. In this case, how to transmitdata is a problem to be resolved in the embodiments of the presentdisclosure.

FIG. 2 is a schematic flowchart 1 of a data transmission methodaccording to an embodiment of the present disclosure. As shown in FIG. 2, the data transmission method includes the following steps.

Step 201: A terminal receives first configuration signaling, anddetermines, based on the first configuration signaling, a first resourceoccupied by first data in a first slot, where a UL/DL type of the firstdata may indicate a transmission direction corresponding to the firstresource, the first resource includes at least one time domain symbol,the first configuration signaling schedules data in N slots includingthe first slot, and N is an integer greater than 1.

In this embodiment of the present disclosure, the first configurationsignaling is multi-slot dynamic scheduling signaling, where themulti-slot dynamic scheduling signaling is DCI and/or a MAC CE.Multi-slot dynamic scheduling signaling may schedule a plurality ofconsecutive slots to transmit data.

In this embodiment of the present disclosure, the multi-slot dynamicscheduling signaling configures a transmission resource (referred to asthe first resource) in a plurality of slots for a type of data (referredto as the first data). For example, the multi-slot dynamic schedulingsignaling configures the following information: eight consecutive slotsare configured, and the third to sixth symbols in each slot are used totransmit UL data. As can be learned, the third to sixth symbols are thefirst resource. It should be understood that the first resource mayinclude one or more symbols. In addition, the symbols in this embodimentof the present disclosure are all time domain symbols such as OFDMsymbols.

In this embodiment of the present disclosure, a UL/DL type of the firstdata implicitly indicates a transmission direction corresponding to thefirst resource. For example, the first data is UL data, and all thesymbols in the first resource are UL symbols. For another example, thefirst data is DL data, and all the symbols in the first resource are DLsymbols.

Step 202: The terminal receives second configuration signaling, anddetermines, based on the second configuration signaling, a transmissiondirection corresponding to each time domain symbol in the first slot.

In this embodiment of the present disclosure, the second configurationsignaling is different from the first configuration signaling, and maybe semi-static UL/DL configuration signaling and/or dynamic slot formatindication signaling.

The semi-static UL/DL configuration signaling is used to configure aslot format, the slot format includes a transmission directioncorresponding to each time domain symbol in a slot, and the transmissiondirection is UL transmission, DL transmission or flexible transmission.

The dynamic slot format indication signaling is used to indicate a slotformat, the slot format includes a transmission direction correspondingto each time domain symbol in a slot, and the transmission direction isUL transmission, DL transmission or flexible transmission.

Herein, the semi-static UL/DL configuration signaling and the dynamicslot format indication signaling both may separately indicate a slotformat. Alternatively, the semi-static UL/DL configuration signaling andthe dynamic slot format indication signaling may be combined to indicatea slot format. When the two are combined to indicate a slot format, adynamic slot format indication can only change a flexible symbol in aslot format indicated by the semi-static UL/DL configuration signaling.

In the foregoing solution, the semi-static UL/DL configuration signalingincludes common semi-static UL/DL configuration signaling and dedicatedsemi-static UL/DL configuration signaling. Further, the semi-staticUL/DL configuration signaling is RRC signaling or SI.

In the foregoing solution, the dynamic slot format indication signalingis a group common PDCCH.

Step 203: If in the first slot, the transmission direction in the firstresource determined based on the first configuration signaling isdifferent from the transmission direction in the first resourcedetermined based on the second configuration signaling, the terminalskips transmitting the first data in the first slot.

Further, that a transmission direction of at least one time domainsymbol in the first resource determined based on the first configurationsignaling is different from a transmission direction of the at least onetime domain symbol determined based on the second configurationsignaling includes: the transmission direction of the at least one timedomain symbol in the first resource determined based on the firstconfiguration signaling is UL transmission, and the transmissiondirection of the at least one time domain symbol determined based on thesecond configuration signaling is DL transmission; or the transmissiondirection of the at least one time domain symbol in the first resourcedetermined based on the first configuration signaling is DLtransmission, and the transmission direction of the at least one timedomain symbol determined based on the second configuration signaling isUL transmission; or in the foregoing solution, to ensure normal datatransmission, the first configuration signaling configures that UL datacan be transmitted in only a UL symbol or a flexible symbol configuredby the second configuration signaling.

In this embodiment of the present disclosure, that the terminal skipstransmitting the first data in the first slot includes a UL case and aDL case. Specifically:

1) If a type of the first data is UL data, the terminal skips sendingthe UL data in the first slot.

2) If a type of the first data is DL data, the terminal skips receivingthe DL data in the first slot.

3) The third configuration signaling is cell-specific RRC signaling.

Step 303: If the second resource and the first resource have a resourceoverlap in the first slot, the terminal determines, based on a presetpolicy, data transmitted in the first slot.

In this embodiment of the present disclosure, that the second resourceand the first resource have a resource overlap in the first slotincludes:

in the first slot, at least one time domain symbol in the secondresource is located in the first resource.

If the second resource and the first resource have a resource overlap inthe first slot, the terminal performs the following data transmissionmanners:

1) If the third configuration signaling is one-slot dynamic schedulingsignaling, the terminal transmits the second data in the first slot.

2) If the third configuration signaling is UE-specific RRC signaling,the terminal transmits the first data in the first slot.

The technical solutions in the embodiments of the present disclosure arefurther described below with reference to specific application examples.

Application example 1. Multi-slot dynamic scheduling signalingconfigured multi-slot transmission and a slot format configured bysemi-static UL/DL configuration signaling. Specifically, a base stationmay configure a slot format by using the semi-static UL/DL configurationsignaling. The slot format includes quantities and positions of ULsymbols, DL symbols, and flexible symbols in each slot. The base stationmay schedule multi-slot data transmission by using multi-slot dynamicscheduling signaling (for example, DCI).

If multi-slot scheduled data transmission is DL transmission, DL data ina slot can be transmitted in only a DL symbol and a flexible symbol in aslot in semi-static UL/DL configuration.

If multi-slot scheduled data transmission is UL transmission, UL data ina slot can be transmitted in only a UL symbol and a flexible symbol in aslot in semi-static UL/DL configuration.

Application example 2. Multi-slot dynamic scheduling signalingconfigured multi-slot transmission and a slot format indicated by adynamic slot format. Specifically, the base station may configure a slotformat by using semi-static UL/DL configuration signaling. The slotformat includes quantities and positions of UL symbols, DL symbols, andflexible symbols in each slot. Based on this, the base station may usethe dynamic slot format to indicate a further configured slot format.Herein, the dynamic slot format can only change a direction of aflexible symbol in semi-static UL/DL configuration. The base station mayschedule multi-slot data transmission by using multi-slot dynamicscheduling signaling (for example, DCI).

If multi-slot scheduled data transmission is DL transmission, DL data ina slot can be transmitted in only a DL symbol and a flexible symbol in aslot indicated by the dynamic slot format.

If multi-slot scheduled data transmission is UL transmission, UL data ina slot can be transmitted in only a UL symbol and a flexible symbol in aslot indicated by the dynamic slot format.

If a transmission direction of a symbol in which data transmissionoccurs in a slot in the multi-slot scheduled data transmission isopposite a transmission direction of a symbol of a slot indicated by thedynamic slot format (transmission directions of one or more symbols of aplurality of symbols corresponding to data transmission are oppositetransmission directions of corresponding symbols in semi-static UL/DLconfiguration, the network device skips sending DL data or receiving ULdata in the slot, and a terminal skips receiving the DL data or sendingthe UL data in the slot.

Application example 3. Multi-slot dynamic scheduling signalingconfigured multi-slot transmission and one-slot dynamic schedulingsignaling configured one-slot transmission. Specifically, the basestation may schedule multi-slot data transmission by using multi-slotdynamic scheduling signaling (for example, DCI) or may schedule one-slotdata transmission by using one-slot dynamic scheduling signaling (forexample, DCI).

If the base station schedules multi-slot data transmission by using DCI,the base station also schedules one-slot data transmission by using DCI,and transmission resources used for one-slot transmission in the slotoccupy some transmission resources used for multi-slot transmission, thebase station performs the one-slot data transmission in the slot, anddiscards multi-slot data transmission.

Application example 4. Multi-slot dynamic scheduling signalingconfigured multi-slot transmission and UE-specific RRC signalingconfigured transmission. Specifically, the base station may schedulemulti-slot data transmission by using multi-slot dynamic schedulingsignaling (for example, DCI) or may schedule data transmission by usingUE-specific RRC signaling. For example, a network uses UE-specific RRCsignaling to configure periodically sent CSI-RSs or periodically sentSRSs.

If the base station schedules multi-slot data transmission by using DCI,the base station configures data transmission by using UE-specific RRCsignaling, and transmission resources scheduled based on DCI in a slotand transmission resources of UE-specific RRC signaling configuredtransmission completely or partially overlap, the base station performsthe multi-slot scheduled data transmission in the slot, and discards theUE-specific RRC signaling configured transmission.

Application example 5. Multi-slot dynamic scheduling signalingconfigured multi-slot transmission and cell-specific RRC signalingconfigured transmission. Specifically, the base station may schedulemulti-slot data transmission by using multi-slot dynamic schedulingsignaling (for example, DCI) or may configure data transmission by usingcell-specific RRC signaling. For example, a network uses cell-specificRRC signaling to configure a transmission resource for transmitting anSSB or RMSI or OSI.

If the base station schedules multi-slot data transmission by using DCI,the base station configures data transmission by using cell-specific RRCsignaling, and transmission resources for multi-slot transmissionscheduled based on DCI in a slot and transmission resources ofcell-specific RRC signaling configured transmission completely orpartially overlap, the base station performs the cell-specific RRCsignaling configured transmission in the slot, and discards themulti-slot data transmission scheduled based on DCI.
